And We indeed gave Moosa the Book after We had destroyed the former generations, having enlightenment for mankind, and a guidance and a mercy, for them to accept advice. 43 (Prophet Muhammad) you were not on the western side (of the mountain) when We decreed the commandment to Moses, nor were you among those witnessing. 44 nay, but [between them and thee] We brought into being [many] generations, and long was their span of life. And neither didst thou dwell among the people of Madyan, conveying Our messages unto them: nay, but We have [always] been sending [Our message-bearers unto man]. 45 And you (O Muhammad SAW) were not at the side of the Tur (Mount) when We did call, [it is said that Allah called the followers of Muhammad SAW, and they answered His Call, or that Allah called Musa (Moses)]. But (you are sent) as a mercy from your Lord, to give warning to a people to whom no warner had come before you, in order that they may remember or receive admonition. [Tafsir At-Tabari, Vol. 20, Page 81]. 46 If (We had) not (sent thee to the Quraish),- in case a calamity should seize them for (the deeds) that their hands have sent forth, they might say: "Our Lord! why didst Thou not sent us a messenger? We should then have followed Thy Signs and been amongst those who believe!" 47 But (now) when the truth has come to them from Us, they say: Why is he not given the like of what was given to Musa? What! did they not disbelieve in what Musa was given before? They say: Two magicians backing up each other; and they say: Surely we are unbelievers in all. 48 Tell them, (O Prophet): "Then do bring a Book from Allah which is a better guide than either of them, and I will follow it! Do so if you are truthful!" 49 If they do not respond to you, then know that they follow only their own desires. Who could be more astray than he who follows his own likes and dislikes with no guidance from God? God does not guide the evil-doers. 50
